中文摘要	We report that the maximum magnetic entropy change Delta S-m, of Tm39Ho16Co20Al25 metallic glass can reach 18.3 Jkg(-1) K-1 under 5 T, which is larger than that of any previously reported metallic glasses and comparable with that of the giant magnetocaloric effect material Gd5Si2Ge2 compound. Even under low magnetic field of 2 T, the Delta S-m of the glass can reach 10.3 Jkg(-1) K-1 which is even larger that of most of other metallic glasses under 5 T. The excellent magnetocaloric effect and refrigerant efficiency together with unique mechanical and physical properties of the metallic glasses indicate they are promising candidate for magnetic refrigerants.
